Christmas came early for "SNL" fans during the holiday episode last night.
Amy Adams treated the audience to an adorable rendition of "We Need A Little Christmas" before former "SNL" cast member Kristen Wiig crashed the monologue -- or as Wiig put it, "showed up uninvited." Adams was sure to remind Wiig that this wasn't the first time the "Bridesmaids" star got in on the action while Adams played host. Back in 2008, the duo performed "What Is This Feeling?" from the Broadway show "Wicked." This time was not much different, aside from the holiday twist, as the two belted out the wrong lyrics to Christmas carols together. Watch the full clip above.
